How does Johanna Michaelsen use imagery in The Beautiful Side of Evil?

In Chapter Nine, the author attends a program that is supposed to teach people to tap into the power of the Alpha Waves produced by the brain (perceivable by scientific tests) and, through relaxation and imagery, increase their psychic perceptions and abilities. The author describes her enthusiastic embracing of the program and its work, including the creation of a mentally imaged "laboratory", and the request for two "counselors" to work with her there.
